Background: Jewel orchid is the common name of several orchid species which can be alike in morphological characteristics, but variable in medicinal properties. At present, two DNA barcode loci, namely, maturase K (matK) and ribulose 1,5-biphosphate carboxylase (rbcL), are intensively utilized for plant identification. However, the discrimination effectiveness of these loci is variable among plant species. This study was carried out to compare the identifying efficacy of these two loci on jewel orchid population collected throughout Vietnam.
Results: The results revealed that 21 jewel orchid accessions studied were segregated into four different species with significant variations. The discrimination power of matK and rbcL markers in this jewel orchid study displayed different efficiency level. The rbcL gene has higher distinguishing potential than either matK gene alone or the combination of both genes.
Conclusion: The findings of this project could provide valuable information that is necessary for classification, plant origin identification, breeding, and conservation program of jewel orchid in Vietnam.

Obesity has been shown to negatively impact cognitive functions, but effective treatments for obesity-induced cognitive impairment are lacking. Natural dietary and plant products, functional foods, and plant-derived compounds have gained attention as potential remedies in part due to the nootropic properties of plants and certain plant-derived agents. This review discusses plant extracts and plant-derived substances that have been shown to ameliorate obesity-induced cognitive impairment in animal models.

is commonly known as a jewel orchid due to its variegated leaves. Easy maintenance of the orchid allows it to be used as a test system for various fertilizers and nutrient sources, including aquaponic water (AW). First, we applied DNA barcoding to assess the taxonomic identity of this terrestrial orchid and to construct phylogenetic trees.

This study investigated conserving an endangered terrestrial jewel orchid using in vitro grown axillary buds. Excised segments of axillary buds (4-5 mm in length) were precultured on a modified Murashige and Skoog (MS) medium supplemented with 0.2 M sucrose for 24 h and osmoprotected in a loading solution for 20 min.

A new species of (Orchidaceae) from Tibet, China, , is described and illustrated here. Molecular phylogenetic results based on one nuclear (ITS) and two plastid markers ( and ) support the recognition of as a new species in GoodyerasubsectionReticulum. Morphologically, the novelty is most similar to , and especially to , but differs by the thick grid lines of the reticulations with a diffused margin on the adaxial surface of the leaf blades, the inflorescence with more flowers, the obliquely obovate-rhombic petals, the yellow or yellowish labellum without a lamella on the blade, and the shorter trichomes on the floral bracts, sepals and ovary.
